A manufacturer has a monthly fixed cost of $50,000 and a production cost of $6 for each unit produced. The product sells for $13/unit. What is the cost function? What is the revenue function? What is the profit function? ?
A. C(x) = 6x + 50,000, R(x) = 13x and P(x) = 7x- 50,000 B. C(x) = 6x + 50,000, R(x) = 6x and P(x) = 7x + 50,000 C. C(x) = 6x + 50,000, R(x) = 50,000x and P(x) = 7x + 50,000 D. C(x) = 13x + 6, R(x) = 6x and P(x) = -7x + 50,000 E. C(x) = 13x + 50,000, R(x) = 50,000x and P(x) = 7x- 50,000
